   Process for the production of drum casings from wooden veneers.
 EMI1.1
 To connect adhesive (also by riveting). When using glue, the connection of the Founnere to each other must be brought about by a constant pressure on the entire wooden casing for several hours so that the glue dries and binds, or the rolled-up casing must be kept in tension until this drying has taken place. This time-consuming process precludes any mass production.



   The subject of the present invention now consists of a process for the production of drum casings from three or more wood veneers, placed in edges, connected by a watertight binder and united by pressing to form a straight or curved panel, the bending in the direction of the grain of the

In addition, this plate can be rolled round, since the.

PATENT CLAIM Process for the production of drum casings from three or more wooden veneers, placed crosswise on top of one another, connected by a watertight binding agent and united by pressing to form a straight or curved plate, whereby the bending takes place in the direction of the fibers of the outer cover veneer, characterized in that the plate After the binding agent has dried, it is subjected to external moistening and heating and is then formed into a cylinder between heated press rollers and bending rollers. ** WARNING ** End of DESC field may overlap beginning of CLMS **.
